In economics, cargo or freight are goods or produce being conveyed â generally for commercial gain â by ship, boat, or aircraft, although the term is now often extended to cover all types of freight, including that carried by train, van, truck, or intermodal container.
What are 'Consumables'. Consumables are goods used by individuals and businesses that must be replaced regularly because they wear out or are used up. They can also be defined as the components of an end product used up or permanently altered in the process of manufacturing, such as semiconductor wafers and basic chemicals.
Almost all of our customers choose this option over the CDs-only option below. The main advantage of owning the consumable workbook (in addition to the CDs) is that it prevents students from having to copy down each problem on a separate sheet, which saves them time and helps them to avoid errors.
